Calibrachoa plant named ‘Wescamagno’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Wescamagno’, characterized by its cascading and vigorous growth habit; freely branching habit; dense and bushy appearance; relatively small leaves; medium-sized flowers; and numerous pink-colored flowers with a red purple-colored circumorbital ring.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Wescamagno’.

BACKGROUND OF THE INVENTION

The present Invention related to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Wescamagno’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program is to develop new vigorous Calibrachoa cultivars with attractive and unique flower coloration.

The new Calibrachoa originated from a cross-pollination made by the Inventor in 2000 of a proprietary selection of Calibrachoa identified as code number 00P150, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa identified as code number 00P093, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor in a controlled environment in Südlohn, Germany as a single plant within the resulting progeny from the cross-pollination.

Asexual reproduction of the new cultivar by terminal cuttings at Südlohn, Germany since 2001, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Wescamagno have not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wescamagno’. These characteristics in combination distinguish ‘Wescamagno’ as a new and distinct cultivar of Calibrachoa:

-   -   1. Cascading and vigorous growth habit.     -   2. Freely branching habit; dense and bushy appearance.     -   3. Relatively small leaves.     -   4. Medium-sized flowers.     -   5. Numerous pink-colored flowers with a red purple-colored         circumorbital ring.

Plants of the cultivar Wescamagno can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa were less vigorous than plants         of the female parent selection.     -   2. Plants of the new Calibrachoa had smaller leaves than plants         of the female parent selection.     -   3. Plants of the new Calibrachoa and the female parent selection         differed in flower color as plants of the female parent         selection had white-colored flowers.

Plants of the cultivar Wescamagno can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa had shorter internodes than         plants of the male parent selection.     -   2. Plants of the new Calibrachoa had darker green-colored leaves         than plants of the male parent selection.     -   3. Plants of the new Calibrachoa and the male parent selection         differed in flower color.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Wescarose, disclosed in U.S. Plant Pat. No. 12,752. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the cultivar Wescarose in the following characteristics:

-   -   1. Plants of the new Calibrachoa were shorter than plants of the         cultivar Wescarose.     -   2. Plants of the new Calibrachoa had smaller and darker         green-colored leaves than plants of the cultivar Wescarose.     -   3. Plants of the new Calibrachoa had smaller sepals than plants         of the cultivar Wescarose.     -   4. Plants of the new Calibrachoa and the cultivar Wescarose         differed in flower color.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Wescaice, disclosed in U.S. Plant Pat. No. 15,345. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the cultivar Wescaice in the following characteristics:

-   -   1. Plants of the new Calibrachoa had shorter and thinner lateral         branches than plants of the cultivar Wescaice.     -   2. Plants of the new Calibrachoa had smaller leaves than plants         of the cultivar Wescaice.     -   3. Plants of the new Calibrachoa and the cultivar Wescaice         differed in flower color.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and for the following description were grown under conditions which closely approximate commercial production conditions during the spring and summer in a glass-covered greenhouse in Südlohn, Germany. Plants were about 20 weeks from planting rooted cuttings and grown in containers. During the production of the plants, the day temperatures ranged from 20 to 25° C., night temperatures ranged from 16 to 18° C. and light levels ranged from 3,000 to 50,000 lux.
